What to do next

  1. Note your version, then check whether it matches the reported pair: the app disconnecting after a second or two, and "Return failed" / "Charging failed (1000011)" at the dock.

    More about this step

    Applies when: the mower is on 2.3.25.12.

    Worked if: you know whether this release's unreported symptoms are what you have.

    Didn't work? Next: step 2 — The release immediately before this one is 2.3.22.28 (April 15,...

    Method: the release thread's owner reports, against a changelog that describes mapping and Smart Charging instead

  2. The release immediately before this one is 2.3.22.28 (April 15, 2026) per Mammotion's own knowledge base. But this is body firmware, and no confirmed manual downgrade path exists, so that number is what to look for if a path ever appears, not something to act on today.

    More about this step

    Applies when: you were about to look for a rollback target.

    Worked if: you are not chasing a rollback that cannot be performed.

    Didn't work? Next: step 3 — Contact support with your version and those two error strings....

    Method: the general rollback guide's own conclusion, and this page's rollback section

  3. Contact support with your version and those two error strings. Tell us as well: neither symptom appears in the manufacturer's changelog for this release.

    More about this step

    Applies when: the drops and docking failures continue.

    Worked if: the case is with support, and the unreported symptoms are on record rather than only in a forum thread.

    Method: this page's own report

Robot body — not the app. See our app vs. firmware vs. RTK guide if you're not sure which one you're dealing with.

Before you start: confirm your mower's current firmware version and note it down. If this rollback doesn't go as planned, you'll want that number to ask for help.

What's been reported

Severe WiFi/4G connection drops after updating to 2.3.25.12: the app disconnects after 1-2 seconds and becomes "completely unusable" for some1. The same reports describe frequent partial docking failures, with "Return failed" and "Charging failed (1000011)" error messages. Neither issue is mentioned in Mammotion's own changelog for this release, which instead describes new mapping and Smart Charging features2.

Rollback procedure

This is the mower's own body firmware, not the phone app. The two update independently, and only the app has a confirmed manual rollback path today. See the mower body firmware section of the general rollback guide for what's actually possible: no confirmed manual downgrade path exists, so 2.3.22.28 (April 15, 2026, the release immediately prior to 2.3.25.12 per Mammotion's own knowledge base) is what to ask Mammotion support for, not a procedure you can run yourself.
